\section{How to access the user interface}  

To access the user interface please open your browser (the application is optimized for the usage with firefox) and enter the url http://host:8080/SimilaritySearchWEB. Thereby "host" has to be replaced by the host name or ip the server is running on. If the server is running on the same machine insert "localhost".

\section{How to use the user interface - Manual}

\subsection{Start Screen}

The start screen offers the option to search for documents without being logged in. If you click on “Register”, a new user is able to register. 
Entered username and password cannot already used by someone else. The system detects this and informs the user. The entry of the password has to be repeated. 
The user is forwarded to the login page.

\subsection{Login Screen}
On the login screen the user is able to login with his generated user credentials. He is redirected to the home interface after clicking submit. 


\subsection{Similarity Search Home}
Generally, the “Go!” button starts the transaction or the request. It is always possible to go back to the home interface by clicking the “Go Back to Home” button.
The option “Logout” lets you leave the web application.

In the home interface the following options are offered. You can search for documents by entering a search query. 
An autocomplete function supports the search request.

\subsubsection{Advanced Search}
The Button “Advanced Search” offers the possibilty to search for a document in a more concrete manner. You can specify in the radiobox which criteria you want to choose 
for searching for a document and additionally whether you want to filter by trustful users or preferences. If you select “Filter by trustful users”, your search only contains results from you or users who share a group with you.
If you select “Filter by preferences” the search results only contain files from categories you chose as preferences.
The search is started by the “Go!” button. As usual it is possible to go back to the home interface by clicking the “Go back to Home” button.

\subsubsection{Upload}
The section “Upload” offers the possibility to upload a file from your local file system. You can add a file description, which could be something like: “Concert from the MET Opera New York”.
You have to select the category like "Jazz" for music. A category can only be created by an 
administrator in his preference settings. The content type can be either music, picture or text.

all matching groups is shown. By selecting one group the user gets more specific information about the group.
The group administrator is shown as well as all its members. You can either join the group if you are not already registered there or leave it. 
In the section “Your Groups” it is possible to create a new group. The current user will be the administrator of this group.
